Final answer:
The wavelength at which the maximum intensity occurs decreases as the temperature increases, due to the inverse relationship between frequency and wavelength when the speed of light is constant.
Step-by-step explanation:
When you increase the temperature of an object, the wavelength at which the maximum intensity occurs changes in accordance with the Wien's Law. As the temperature increases, the frequency of light providing the greatest intensity also increases. This relationship is inverse as per the equation v = fλ where v is the speed of light, f is the frequency, and λ is the wavelength. Since the speed of light remains constant, an increase in frequency will result in a decrease in wavelength. This principle is validated by the observation of the peak emission shifting towards shorter wavelengths with higher temperatures, which means the wavelength decreases.
